Pepper (Bell Capsicum annum) Yep. Feed 'em. But I've never seen a discussion about iguanas eating other typs of peppers such as super-hot peppers like Jalepeno or Ghost Peppers.

You mean pepper LEAVES? I never heard. Force-feed some to your cat and see what happens. But plant poisons are not noxious to all species of vertebrates. Here in California I've watched tree squirrels sit and seriously eat amanita death caps.
